The Tsugaru Strait Open Water Swim Challenge -- Our virtual swim simulator plots your open water swim course on a map. Sign up using the login link at the top of the screen. Then invite your fiends to join you on a virtual swim. After enrolling, use our swim calorie calculator to compute distance, pace and calories burned. Then save your swim in our swim workout log and apply the distance and calories to a open water swim challenge.

This swim calories calculator uses distance, time, weight and swim stroke to calculate calories burned. Please be aware that the calories burned is an estimate. Actual calories burned will depend upon many other factors, such as general health, water temperature, stroke efficiency.
